What is a rock tumbler?

A rock tumbler is a device that is used to polish rough rocks and turn them into smooth and shiny stones. It works by rotating rocks in a barrel with grit and water for an extended period of time, usually weeks or even months. The process of tumbling mimics natural weathering but at a much faster rate, resulting in beautifully polished stones.

Why choose National Geographics Rock Tumbler?

There are many rock tumblers available in the market, but what sets National Geographics Rock Tumbler apart from others is its quality and durability. The barrel of this tumbler is made of high-quality rubber that reduces noise during operation and makes it more durable compared to plastic barrels used in other tumblers. The motor used in this machine is also powerful enough to handle large loads of rocks without overheating or malfunctioning.

What comes with the kit?

The National Geographics Rock Tumbler comes as a complete kit with everything you need to start tumbling right away. The kit includes one pound of gemstones (four different types), four polishing grits (coarse, medium, pre-polish, and polish), jewelry fastenings, instructions booklet, and a learning guide written by geologists.

As someone who has never used a rock tumbler before, I found the National Geographics Rock Tumbler very easy to use. The instructions booklet provided with the kit was clear and concise, making the process straightforward even for beginners like me. All you need to do is add the rocks, grits, and water in the barrel according to the instructions provided and let the machine do its job.

How long does it take to tumble rocks?

The tumbling process can take anywhere from three weeks to two months depending on how smooth you want your rocks to be. However, patience pays off as the end result is well worth the wait.

Any downsides?

One minor downside that I noticed while using this rock tumbler was that it can be quite noisy during operation due to its powerful motor. However, this can be easily solved by placing a towel underneath the machine to absorb some of the vibrations.

The Verdict
